Bug #: 30974
           Summary: No backtrace with Visual C++ 2010 .pdb files in large
                    app; "Unsupported type 1404 in STRUCT field list"
           Product: Wine
           Version: 1.5.6
          Platform: x86
        OS/Version: Linux
            Status: NEW

        ReportedBy: [e-mail]
    Classification: Unclassified

When trying to get a backtrace from a large proprietary app built with
Visual C++ 2010, wine's backtracer issues the errors seen in bug 30973
along with a few more, e.g.

fixme:dbghelp_msc:codeview_add_type_struct_field_list Unsupported type 1404 in
STRUCT field list
fixme:dbghelp_msc:codeview_fetch_type Cannot locate type 103
fixme:dbghelp_msc:codeview_get_type Returning NULL symt for type-id 103
fixme:dbghelp_msc:codeview_snarf S-Udt nullptr_t: couldn't find type 0x103

and fails to generate a useful backtrace.
